Commands Description
AT*EAM Accessory Menu adds a persistent menu item to the phone menu structure. When the menu is selected, the unsolicited result code *EAAI is sent.
Set command:
AT*EAM=<persistent_menu_item_text> Test command:
AT*EAM=? Shows if the command is supported. Parameter:
<persistent_menu_item_text>: Character string; the menu item text in the additional menu. Example: AT*EAM=menu_1
OK
AT*EAM=? OK

Advantages
Control over the various devices installed in
the office or home
To make effective time management and to
reduce

Conclusions
The design consists of a mobile phone, Bluetooth,
computer and a microcontroller. The home appliances
are controlled by the microcontroller, which operates
according to the user commands received from the
mobile phone or Computer via Bluetooth.
Such a design transforms a mobile phone into a portable
remote controller for home automation. The primary
contribution of this system is to economically have a
remote control system for home/ office devices that are
controlled using mobile phone and computer. The status
of the devices can be monitored and controlled by using
mobile phone which is within the range of Bluetooth.
